It happened! Leonardo Dicaprio finally won the Oscar award for Best Actor and his acceptance speech said far more than gratitude. He spoke about how real climate change is and encouraged everyone to take action about that important issue. It isn't new for DiCaprio to be interested about environmental subjects, he's been into it since 1998 when he founded the Leonardo DiCaprio Foundation to help biodiversity and threatened ecosystems.

'The Revenant' gave DiCaprio a close look to the dreadful impact of climate change as they couldn't find snow! DiCaprio said they had to go to southern tip of Argentina just to be able to find snow to complete the film. The cast and crew were often thwarted by temperatures that flexed 'from hot to cold'.

DiCaprio also thanked those who have been key to his career, like Martin Scorsese. The pair has a history of great films since 2002: 'Gangs of New York', 'Shutter Island', 'The Aviator' (2004 Nominee, Actor in a Leading Role), 'The Departed' and 'The Wolf of Wall Street' (2013 Nominee, Actor in a Leading Role). And there's more to come, they have teamed up for a sixth movie called 'The Devil in the White City', which will be about the serial killer H. H. Holmes and his 'Murder Castle'.

Here is the transcript of Leonardo DiCaprio's acceptance speech:

Thank you all so very much. Thank you to the Academy, thank you to all of you in this room. I have to congratulate the other incredible nominees this year for their unbelievable performances. The Revenant was the product of the tireless efforts of an unbelievable cast and crew I got to work alongside. First off, to my brother in this endeavor, Mr. Tom Hardy. Tom, your fierce talent on screen can only be surpassed by your friendship off screen. To Mr. Alejandro Innaritu, as the history of cinema unfolds, you have forged your way into history these past 2 years... thank you for creating a transcendent cinematic experience. Thank you to everybody at Fox and New Regency…my entire team. I have to thank everyone from the very onset of my career…to Mr. Jones for casting me in my first film to Mr. Scorsese for teaching me so much about the cinematic art form. To my parents, none of this would be possible without you. And to my friends, I love you dearly, you know who you are.

And lastly I just want to say this: Making The Revenant was about man's relationship to the natural world. A world that we collectively felt in 2015 as the hottest year in recorded history. Our production needed to move to the southern tip of this planet just to be able to find snow. Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating. We need to support leaders around the world who do not speak for the big polluters, but who speak for all of humanity, for the indigenous people of the world, for the billions and billions of underprivileged people out there who would be most affected by this. For our children’s children, and for those people out there whose voices have been drowned out by the politics of greed. I thank you all for this amazing award tonight. Let us not take this planet for granted. I do not take tonight for granted. Thank you so very much.
